Protein Structure
UniProt Annotation
Function Protects the body from potent vasoactive and inflammatory peptides containing C-terminal Arg or Lys (such as kinins or anaphylatoxins) which are released into the circulation.
Subcellular Localization Secreted, extracellular space.
Disease Associations Carboxypeptidase N deficiency (CPND) [MIM:212070]: Patients affected present some combination of angioedema or chronic urticaria, as well as hay fever or asthma, and have also slightly depressed serum carboxy peptidase N, suggestive of autosomal recessive inheritance of this disorder. {ECO:0000269PubMed:12560874}. Note=The disease is caused by mutations affecting the gene represented in this entry.
Tissue Specificity Synthesized in the liver and secreted in plasma.
